- 2 Claims. (01. 146-3) This invention appertains to new and usefulimprovements in juice extractors.

The principal object of the present invention is to provide a juiceextractor for extracting juice from fruits of various kinds which inoperation will be more convenient and effective than present dayextractors;

Another importantbobject of the invention is to provide an extractor ofthe character stated which in operation will not only take care of thejuice and prevent waste thereof, but which in operation will also takecare of the waste materials and effect an eflicient discharge of thesame from the machine.

These and other important objects and advantages of the invention willbecome apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a vertical sectional view through the machine.

Figure 2 is a top plan view.

Figure 3 is a sectional view on the line 33 of Figure 2.

Figure 4 is a sectional view on the line 4-4 of Figure 1.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 represents the shell through the side ofwhich projects the switch 6 for controlling the motor I. The shell 6 isprovided with the bottom plate 8. An annulus 9 is clamped about themotor I and tie bolts therefrom extend upwardly through the shoulderportion of the annular frame It) and also through the ring 1! whichsupports the dome or cover l2. Arms I! extend outwardly from the ring IIand have upstanding pins ll thereon which extend into recesses ofthickened portions I 5 of the dome l2. The pins ll are provided withshoulders l6 thereon with which spring detents H on the thickenedportions l5 can engage to detachably hold the dome or cover in position.

A tubular part l8 depends from the top of the dome or cover 12 andsurrounds an opening in 45 said top part and this tubular member isconnected with portions of the dome or cover l2 by the reinforcing ribsIS. A feed tube 26 has a press fit in this tubular part I! and isadapted to receive the fruit or objects to be shredded or formed intopulp. This tube has its lower end but slightly spaced from the shredderplate 21 which has its top surface roughened as at 28 for shredding orpulping the fruit resting thereagainst in the tube 26. This plate 21 hasa hub 55 21' which fits over the hub III of a fan 'H, the

hub of the fan being splined to the shaft 30 of the motor 1, said fanacting to keep the motor cool. The hub 21 is connected withthe hub 16 bymeans of a split spring ring 29v having a tongue 29' thereon whichextends through slots in the hubs 21- and ID, as shown in Figure 4. Theplate 21 forms the major part of the bottom of a circu-- lar extractorbasket l9 which has its side wall flaring upwardly and provided with theperforations 2i and adjacent the top said side wall curves 10 inwardlyand terminates in an overhang rim 20, the perforations stopping at theupper terminal of the outwardly flared part. Numeral 22 represents thepan from which extends the spout 23 through which the extracted juicescan pass. 15 Said pan surrounds the basket ,and has a large centrallyarranged opening surrounded by a flange which 'engages the upper end ofthe annular frame It] and a portion of the pan rests on the ring II. V20 Numeral 24 represents the deflector plate having upturned end walls25. The deflector plate 24 is carried by the lower portion of the tube26 and said plate is formed with an upwardly extending tubular part 24'which fits over the lower 25 end of the tube 26 and is connected theretobya pin and bayonet slot connection shown generally at 25'.

A i split collar-like structure 3| extends inclinedly from the dome l2in substantially a 30 chordal direction. This collar 3| is split andprovided with lugs through which a clamp screw 32 is disposed.

An ejector tube 33 extends through this collar and is held in place bythe same. The tube ex- 35 tends into the dome l2 and partly into thebasket l9 and has a thin lip forming portion 34 arranged adjacent aportion of the rim 20 of the basket.

As will be understood an object to be shredded or pulped is placed inthe tube 26 so that it will rest on the roughened surface of the plate21 and as the plate 21 with the basket revolves the fruit or otherobjects will be shredded or pulped and this pulp with the juice will bethrown by centrifugal force against the perforated walls of the basketand this centrifugal force will cause the juice to pass through theperforation and enter the pan 22 and pass therefrom through the spout 23into the receptacle placed under the spout. The pulp collecting on theslide wall of the pan will climb up the same-due to the wall flaringoutwardly and upwardly until the pulp reaches the inwardly and upwardlyslopingpart of the wall which is not perforated. -At this point theupward movement of the particles or pulp will be retarded and theparticles will begin to pack under the overhanging rim 20. The sharpenedpart or lip 34 of the discharge pipe 33 will enter this packed formationand as the pan revolves the pipe will scoop up the particles and theywill pass through the pipe to the outer end thereof. A suitablecontainer can be placed under the outer end of the pipe 33 to collectthe dry pulp. Any particles of the: pulp missing the discharge tube willbe driven oil the overhanging flange 20 and will fly into the curvededge portion of the cover or dome l2. Only a small percentage of thepulp, if any, will fail to pass through thetube 33.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A juice extractor comprising a supporting member, an extractor panincluding a bottom forming plate having teeth on its upper surface andupwardly flaring annular side walls, the upper portion of which curvesinwardly to provide an overhanging rim, the flaring portion havingperforations therein, means for rotating the extractor pen, a hopper forholding an object from which the juice is to be extracted in contactwith the upper portion of the plate, a second pan surrounding theextractor pan for receiving the juices passing through the perforations,the pulp thrown against the upwardly flaring side wall passing up saidwail onto the inwardly curved portion, a cover device extending over theupper ends of the pans and carrying the hopper and a tube supported bythe cover device and extending tangentially inwardly and downwardlythrough the cover device to a point adjacent and inwardly of theoverhanging rim of the extractor pan for removing the pulp collecting atthe rim.

2. A juice extractor comprising a vertically arranged casing, a motorsupported in the casing and having its shaft vertically arranged andlocated at the top of the casing, an extractor pan having a bottom partformed of a horizontal plate having'teeth in its upper surface and anannular side wall flaring upwardly and then curving inwardly, theflaring part having perforations therein, the central portion of the panbeing connected with the motor shaft to rotate therewith, a second pansupported from the top of the casing and surrounding the extractor panand having a discharge spout, a cover member and means for removablysupporting the same from the top of the casing and said cover memberextending over the two pans, a hopper passing through the cover memberand supported thereby and extending to a point adjacent the uppersurface of the toothed plate for holding an object from which the juiceis to be extracted on the plate, a baffle plate supported from thehopper and extending across the bottom forming part of the extractor panslightly spaced above the same and having its edges curved upwardly andlocated adjacent the perforated part of the side wall of the extractorpan, a tangentially arranged discharge tube carried by the cover memberand extending downwardly and inwardly therethrough to a point adjacent arim portion of the extractor pan for receiving the pulp climbingupwardly along the side wall of the pan to the rim thereof.
